Duplex stainless steel plate is a specialized variant within the stainless steel plate category, characterized by its duplex (austenitic-ferritic) structure. Comprising elements like chromium, nickel, and molybdenum, it boasts exceptional corrosion resistance and strength. This unique structure endows the stainless steel plate with outstanding corrosion resistance, strength, and stress corrosion resistance. Widely utilized in marine engineering, chemical equipment, the oil and gas industry, and similar sectors, duplex stainless steel plates are favored in projects necessitating both high strength and corrosion resistance.
Application of Duplex Stainless Steel Plate contains construction, container manufacturing, household appliances and furniture, vehicle and vessel manufacturing, machinery structure parts, manufacturing shells of motors.
High Corrosion Resistance: Duplex stainless steel plate, comprising elements like chromium, nickel, and molybdenum, exhibits outstanding corrosion resistance. Its dual-phase structure enables exceptional performance in challenging environments such as acids, salts, and corrosive gases. Compared to traditional austenitic stainless steel, duplex stainless steel plates offer enhanced corrosion resistance, thereby extending equipment service life.
Good Welding Performance: Duplex stainless steel plate demonstrates excellent welding performance, suitable for various welding techniques including arc welding and TIG welding. Its dual-phase structure minimizes the occurrence of cracks and pores during welding, ensuring stable joint quality and enhancing product reliability and safety.
High Strength and Hardness: Duplex stainless steel plates possess superior strength and hardness compared to austenitic stainless steel. This characteristic makes them ideal for projects requiring robustness and durability, such as marine engineering and chemical equipment applications. Their resilience ensures reliable equipment operation even in harsh environments.
